Chitosan is a biodegradable and biocompatible natural polymer derived from chitin, typically extracted from crustacean shells such as shrimp or crab. It is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine and N-acetyl-D-glucosamine units. Due to its inherent cationic nature and excellent biocompatibility, Chitosan functions as a flocculant, chelating agent, antimicrobial agent, and film-forming material across a wide range of industries including water treatment, agriculture, pharmaceuticals, cosmetics, and food processing.
